Ad Hoc isn't what companies are supposed to use. Ad Hoc is for developers and classroom situations. The solution for the enterprise is another distribution method all together that's not publicly available (only for companies > 500).
And as for little known, I have no idea why they went for that angle. Steve Jobs presented all three methods in his keynote. Ad Hoc is used by almost all developers, but has very very limited use outside of that (thanks to the 100 user cap, which is utter bullshit).
